Upon examination of the physical condition and characteristics of any property subject to this article, and upon written notice to the owner and/or principal occupant thereof, the proper official of the local fire district may require a key box to be installed in a specific location whenever access to or within a structure or an area is unduly difficult because of secured openings or where immediate access is necessary for lifesaving or firefighting purposes.
